Adjust Valve Lash (Diesel Engine - Solid Valve Lifters)

After a fresh rebuild, I can finally adjust the Valve Lash on the rocker arm assembly of the Yanmar 3-cylinder diesel engine. For this, I will need to set each piston to "Top Dead Center" and make sure the gap between the rocker arm and the valve cap is set to the specifications of the Yanmar Service Manual.

Adjusting the valve lifters in this manner can be done to ANY solid lifter engine setup! (This is not the same as a hydraulic valve lifter!)

THANK YOU THANK YOU THANK 1000 TIMES THANK YOU! I am a deisel mechanic, but i had never seen one of these until i bought a chinese tractor. Usually the no. 1 cylinder is at the front, hence my 3 day long confusion. I did what you said at the rear one, and BANG it fired right up! Thank you so much! I'd kiss you if i could!

Another helpful video for one of my engines. I never checked the valve lash on my tractor and maybe it's time to do that now! Thanks WR!!

[scottyscotty]

Great video, clear and informative, thanks!

[briant]

Thank you my friend dropped a push rod now we have to fix it

[happyrecluse]

Great vid Andreas, how do you tell if the lifters are solid or hydraulic?

[pingpong]

I have a Yanmar 3TNV80F engine in an excavator - how do you figure it out when you have a fan on one side and the hydraulic pump on the other?

[pingpong]

When you tighten the nut - do you hold the screw steady (in one position), or are you allowing it to move a bit with the nut? Last time I did a valve job, I noticed the clearance always increased a fraction as the nut was tightened and I ended up having to redo a few times to get it right...

[jasoncraig]

Awesome video Andreas! Thanks for showing this! Could you do this on a flathead engine? Preferably the Kohler kt17.- Jason.

Good morning, I have a question. I am repairing a Yanmar 4TNV88-BSTX engine. I would like to know what the valve clearance is for this engine, please, and the sequence.

Hallo, I have a question. I am repairing a Yanmar 3D72-2b engine. I would like to know what the valve clearance is for this engine, please, and the sequence.

Do you know where I can get engine parts for a 3T75U yanmar 1610D tractor?

[dc-wpoc]

You seem to indicate that tightening the nut, closes the gap on the feeler gauge @7:10 - 7:20. It does not.
The nut tightens to hold the adjusting bolt in place. It is the bolt, adjusted by the flat head screwdriver, that adjusts the gap.
That is why you were not feeling any difference before and after "tightening" the nut.

Good morning, I think I need a little more explanation. Top dead center is both valves shut and the piston fully extended at the top of the stroke. I’ve heard top dead center on the exhaust stroke vs compression stroke. Great video love the detail and btw your engine looks like a show piece! Perhaps I answered my own question 🤦.

Hello I need help setting the spill timing on my yanmar please help

[isaacperezR]

One question, my brother, what is the oil pressure of the Yanmar 4TNV88 engine?

[jorgesoto]

Hello I have a question so when you adjust the next cylinder #2 cylinder needs to be on top dead to be adjusted. ?

[headpainter]

Aren't diesels 4 stroke engines? Intake, compression, power then exhaust. Just no spark plug. You said set/ check valve lash then rotate engine 180 degrees then check again. Wouldn't it be on exhaust stroke at that point and valve under compression? Just trying to get it right in my head. Thanks alot.

[bertwilson]

Why are you calling the cylinder at the back of the engine Cylinder #1? I've never seen an engine numbered this way.

[HazeljoySabinosa]

How about 2 and 3. Valve clearance. The same 1
